The most important requirement for the controller of a prosthetic arm is that it has a high fidelity discriminator where the motion control may be performed open loop using EMG signals as a control source. Therefore, it is very effective method to reduce the influence of misclassification of classifier for the total system performance. This paper presents the new function discrimination method which combines MLP classifier and frizzy filter by stages for the requirement. The major advantage of MLP is a consistent learning capability for the easy adaptation to environments. The fuzzy filter uses all informations of MLP outputs and prior EMG activity informations which increase as the experience increases. That property is superior to one which uses maximum output of MLP in view of information amounts and quality. Simulation result shows that proposed method is superior to the probabilistic model, MLP model and the combined model of both in the respect of discrimination quaity.

This study is to evaluate the public drinking water service systematically, to improve customer satisfaction level, also overcoming the limitations of the existing method often relying on the satisfaction measurement subjectively. Thorough the rigid quality control of the service and its effect on civil affairs administration, we conclude that quality of the public service has an influences on the customers' satisfaction, which play a role to intensify the confidence and support of the civil administration by its appropriate management. Thus quality control management itself has its own value in that the satisfaction and confidence of the service result from the quality. The new model can be utilized as a Service Quality Index for the public drinking water service. To enhance the customers' satisfaction and confidence of the water suppliers, it is very useful that they reflect the customers' needs exactly through the service quality control regularly.
